Glasir (UTC51-03B) was a Class 4 Planet surveyed by Catherine Sakai for Universal Terraform in 2259. Sakai arrived over Glasir three weeks after her puzzling survey of Ymir, having still not received a response from the company regarding her report of the unusual activity at her last survey site. Her survey of Glasir on the other hand managed to turn up a significant amount of Quantium 40, proving to be an excellent prospect for mining.
